Amos Nathan Tversky (Hebrew: עמוס טברסקי; March 16, 1937 – June 2, 1996) was an Israeli cognitive and mathematical psychologist and a key figure in the discovery of systematic human cognitive bias and handling of risk.
Other participants judged the probability of death from a natural cause was 58%. Natural causes are made up of precisely cancer, heart attack, and "other natural causes," however, the sum of the latter three probabilities was 73%, and not 58%. According to Tversky and Koehler (1994) this kind of result is observed consistently. [2]
Prospect theory is a theory of behavioral economics, judgment and decision making that was developed by Daniel Kahneman and Amos Tversky in 1979. [1] The theory was cited in the decision to award Kahneman the 2002 Nobel Memorial Prize in Economics .
The dual process theory may also play a role as negative framings evoke less heightened responses, leading to the deployment of the implicit processes. The implicit process is found to be frame-sensitive, and thus may be the reason why framing is pronounced in negative frames for older adults.
In another study done by Tversky and Kahneman, subjects were given the following problem: [4] A cab was involved in a hit and run accident at night. Two cab companies, the Green and the Blue, operate in the city. 85% of the cabs in the city are Green and 15% are Blue.
Loss aversion was also used to support the status quo bias in 1988, [9] and the equity premium puzzle in 1995. [10] In the 2000s, behavioural finance was an area with frequent application of this theory, [ 11 ] [ 12 ] including on asset prices and individual stock returns.
The theories behind reference class forecasting were developed by Daniel Kahneman and Amos Tversky. The theoretical work helped Kahneman win the Nobel Prize in Economics. Reference class forecasting is so named as it predicts the outcome of a planned action based on actual outcomes in a reference class of similar actions to that being forecast.
Researchers have traced the cause of the disposition effect to so-called "prospect theory", which was first identified and named by Daniel Kahneman and Amos Tversky in 1979. [3] Kahneman and Tversky stated that losses generate more emotional feelings which affect individual than the effects of an equivalent amount of gains.
